Compatible replacement for Testo analysers

This lithium-ion cell is built to fit the Testo 310, 320, 327, 330, 350, 870 and 870-1 instruments. It replaces original part numbers 0515 0046, 0515 0100, 0515 0114 and 0554 1087. Technicians who service flue-gas analysers or thermal imagers can swap the pack without sourcing the OEM unit.

Voltage and capacity limits of the 3.7 V chemistry

The pack delivers 3.7 V nominal and 3400 mAh, giving 12.58 Wh of stored energy. Runtime scales directly with the host instrument’s current draw, so heavy backlight or sensor use will deplete it faster than light logging. No higher-capacity variant exists in this form factor, so users needing longer shifts must carry a spare.

Slim black housing with direct-fit contacts

The black casing measures 74.50 mm by 20.80 mm by 28.50 mm and slides into the battery bay of each listed model without adapters. Spring-loaded terminals on the device engage the cell’s flat contacts, so insertion is a single-handed motion. The pack ships new and is ready for immediate calibration cycles.
